任何人都可以帮助将这一小块VB.NET转换为VBScript,我没有意识到我在编写测试版应用程序时我将要使用的应用程序是VBScript =(
代码从数据库中获取一个表,然后写几行,然后将表写入制表符分隔文件。我知道我可能必须完全用Lambda重写部分?我可能要重新开始,但如果有人能做到这一点,我会很感激!
Private dataTable As New DataTable()
Protected Sub Page_Load(sender As Object, e As EventArgs)
PullData()
End Sub
Public Sub PullData()
'Get data from DB into a DataTable
Using conn As New SqlConnection("Server=.\sqlexpress;Database=DB;User Id=User;Password=Password;")
Using cmd As New SqlCommand("SELECT areaID as 'Pond Number', storageDescription + SPACE(1) + areaID as 'Pond Name', " & vbCr & vbLf & "case when fishWeight = 0 then 0 else 1 end as 'Pondis Used', 1 as 'Volume', " & vbCr & vbLf & "FeedDensity AS 'Feed Density',round(cast(FeedDensity * revolution as float(25)),2)/*cast as float for correct rounding*/ AS 'Feed Multiplier'," & vbCr & vbLf & "feedType as 'Feed Type', feedName as 'Feed Name', batchID AS 'FishBatchCode'" & vbCr & vbLf & vbCr & vbLf & "FROM dbo.vwStorageMASTER" & vbCr & vbLf & vbCr & vbLf & "WHERE fkLocationID = 1 AND fkStorageIndicator <> 3 ORDER BY sequenceNumber ASC", conn)
conn.Open()
Dim da As New SqlDataAdapter(cmd)
da.Fill(dataTable)
End Using
End Using
'Output tab-delimited
Dim delim As String = vbTab
Dim sb = New StringBuilder()
sb.AppendLine("Trafalgar Master File" & vbCr & vbLf & vbCr & vbLf)
sb.AppendLine(String.Join(delim, "Number of Ponds: ", dataTable.Rows.Count.ToString() & vbCr & vbLf & vbCr & vbLf))
sb.AppendLine(String.Join(delim, dataTable.Columns.Cast(Of DataColumn)().[Select](Function(arg) arg.ColumnName)))
For Each dataRow As DataRow In dataTable.Rows
sb.AppendLine(String.Join(delim, dataRow.ItemArray.[Select](Function(arg) arg.ToString())))
Next
'Prompt user to download tab-delimited file
Dim FileName As String = "test.xls"
Dim response As System.Web.HttpResponse = System.Web.HttpContext.Current.Response
response.ClearContent()
response.Clear()
response.ContentType = "text/plain"
response.AddHeader("Content-Disposition", "attachment; filename=" & FileName & ";")
response.Write(sb.ToString())
response.Flush()
response.[End]()
End Sub

虽然VB.Net和VBScript共享相似的语法,但它们使用的对象完全是不同的动物。 Vbscript不了解System.Web,System.Data,StringBuilder等。您可能希望查看VB6语法和后期绑定的CreateObject语法来创建AdoDb对象。

这就是我为我的应用程序重写它的方式。最后我基本上重新开始,但结果几乎相同;
